whats the biggest cam i can run?
#2
I read where anything (LS2) with stock pistons stay at .600 or less. Any more & the clearance starts getting close
so any valve float would contact the piston. They listed duration numbers also being a factor if the numbers are too big.

Man your combo sounds like a deathtrap.
Not really just wanted to use your name.
Well... You asked what is the biggest cam you can run w/o flycuting.
That is a impossible answer to be 100% sure. Many of us could give a accurate guess, but to be 100% wouldn't happen.
You have increased the valve size on the intake, do you mind if I ask why?
Why do a valve job, and bigger valves and not port, mill, etc the heads?
Especially if your now flycuting the pistons, I would take the heads right to the machine shop and have them milled to raise your compression somewhere around 11.5:1. For a LS2 motor with LS2 heads that is only about 20-25 thous mill. OR I would run a .040 gasket and not mill the heads at all.
Have you considered spending a little extra money and buying a set of Trickflows or ETP heads? These both free up additional P/V clearence over stock heads which would save you from having to spend the money/time doing the flycuting.
I have seen some great results with the cam you choose, and even better results with added compression, and aftermarket cylinder heads with that cam.

well i guess i could give a little more info lol. now it looks like im going with a 2.040 intake valve since im going with the tea stage 2 heads. im wanting to keep my compression around 10.5:1 because i plan to spray a 100 shot as well. the flow #s are almost identical to 215 trick flow so im hoping for the same out come

Well on a stock LS2 shortblock with a 243 head your gonna be just under 11:1 as the LS2 motor's have 10.9:1 CR.
Also flow numbers aren't everything.
TEA ports the trick flow heads.
I deal with both company's, and even Brian Tooley will tell you the trick flows out perform their ported LS6 heads. It is a tough comparision. You dealing with 2 completly different heads, and port designs.
For what your spending on the LS6 ported heads a few extra hundred and you could be in a set of trick flows, especially after you sell the stock GM heads.
And there are hundreds of 11:1+ CR setup with nitrous doing just fine.
